The reinsurance contracts in the insurance market have been playing an important role in the last couple of decades. One of the most important reinsurance contracts is the stop-loss reinsurance. It has an interesting property from the insurer point of view such that it is optimal if the criterion of minimizing the variance of the cost of the insurer is used. The word ‘optimality’ takes many researcher’s attention so that optimal reinsurance contracts under different assumptions have been investigated for decades For instance, some researchers used utility functions to find the optimal contract while the others use aggregate claims with many different distributions such as gamma and translated gamma distributions. This study aims to examine the stop-loss contracts with priority and maximum under the assumption the aggreate claims with normal distribution. The dependence between the cost of the insurer and the cost of the reinsurer is taken into account by implementing traditional dependence measures. Additional to these, the impact of tail dependence captured by copula approach is investigated. The deterministic retention is found when the correlation between the cost of the insurer and the cost of the reinsurer is maximum. Moreover, if the contract includes a maximum, the converging of the correlation of the parties is examined according to the distance between the maximum and the priority.

Risk Classification with Artificial Neural Networks Models in Motor Third Party Liability
Yıldırak, Şahap Kasırga; Kestel, Sevtap Ayşe; Gür, İsmail (null; 2019-06-29)
One of the most fundamental requirements in todays insurance sector is the determination of fair premium for the insured. In order for this purpose to be fulfilled, the correct risk classification is required for each insured in the portfolio. By the realization of correct risk classification, the insured can continue to be provided insurance services with more suitable pricing, while the insurance companies will have the opportunity to provide the correct person with the correct insurance and carry out fin...
Uncertainty assessment for the evaluation of net present value: a mining industry perspective
Erdem, Özge; Demirel, Nuray (2012-05-01)
The investment decisionmaking process in the insurance and finance industries is affected by new advances such as simulation techniques. These advances have improved the discounted cash flow method (DCF). In DCF, a dynamic and flexible model construction is not possible because it does not consider uncertain conditions. Each project should be evaluated taking into account the related uncertainties because the related uncertainties determine the characterization of the project. Related uncertainties can be p...
Utilization of outlier-adjusted lee-carter model in mortality estimation on whole life annuities
Yavrum, Cem; Selçuk Kestel, A. Sevtap.; Department of Actuarial Sciences (2019)
Annuity and its pricing are very critical to the insurance companies for their financial liabilities. Companies aim to adjust the prices of annuity by choosing the forecasting model that fits best to their historical data. While doing it, there may be outliers in the historical data influencing the model. These outliers can be arisen from environmental conditions and extraordinary events such as weak health system, outbreak of war, occurrence of a contagious disease. These conditions and events impact morta...
Clustering Influence On MTPL Premium Estimation Using Credibility Approach
Kızıloğlu, İsmail Onur; Kestel, Sevtap Ayşe; Yıldırım Külekci, Bükre; Department of Actuarial Sciences (2023-1-27)
Pricing is one of the crucial aspects of the insurance industry. There are compulsory regulations on Motor Third Party Liability Insurance in Türkiye. After the cap premium, the significance of correct pricing for the profitability of the companies has increased even more. In this thesis, premiums are estimated quarterly using Bühlmann and Bühlmann-Straub credibility methods for the cities of Türkiye. First, the cities are sorted according to the total number of claims and divided into at least 3 and at mos...
Valuation of life insurance contracts using stochastic mortality rate and risk process modeling
Çetinkaya, Şirzat; Hayfavi, Azize; Department of Financial Mathematics (2007)
In life insurance contracts, actuaries generally value premiums using deterministic mortality rates and interest rates. They have ignored them stochastically in most of the studies. However it is known that neither interest rates nor mortality rates are constant. It is also known that companies may encounter insolvency problems such as ruin, so the ruin probability need to be added to the valuation of the life insurance contracts process. Insurance companies should model their surplus processes to price som...
